APPARATUS FOR RECORDING COMPILING STATISTICAL DATA.

I To all whom it may concern Be it known that we, WAYLAND B. CLARK p I Apparatus for Recording and Compiling Statistical Data; and we do hereby declare the .followin -to be a full, clear, .and exact description 0 the invention, such as will enable "others skilled in the art to which it appertains to make and use the same.

The present'invention'relates to apparatus for "recording and accumulatin .or compilin statistical data, and has or its main ob eet to provide improved apparatus of this character involving such noveLfeatures of v construction and operation as will render the apparatus capable of recording and collectin oraccumulating data of practically any kmd and'in practically an unlimited number of dilferent ways. 11 other words; the data may be recorded in a large number of predetermined ways and may later'be accumulated and registered by mechanism which is capable of selecting and re 'stering same, depending upon how said mechanism is set to operate. The setting of the accumulatin and registering mechanism for the record data may be such that various combinations of recorded data may be accumulated and registered, such combinations being practically infinite in number. The possibilities of the apparatus are, therefore, so

unlimited as to render the apparatus of vast commercial importance for uses analogous to that whichwill hereinafter be specifically set forth.

The apparatus itself comprises three main parts or groups of mechanism. The first part is'a so-called punching machine through su' as paper, is sired data is to be recorded. Perforations are punched in such str p,

predetermined positions, such "that for giveninformation or'data, the perforations are ar- Speclflcation of Letters latent.

ranged in a definite and predetermined pattern. qThe second part of the apparatus comprises a so-calledselectorthrough which the record strip .is passed when it is desired to collect any or all of the, data recorded upon the record strip. The selector is so constructed that as the record strip is passed 'therethrough, electric circuits will be controlled by the perforations in the record strip in :such a manner as to complete certain predetermined electric circuits for given PGIfOI'QtlOIlS. or arrangements of perforations on the record strip. ,As it is'the per-.

forations in the record'strip which permit the electric circuits to be completed, the recordstrip itself is anon-conductorof-electricity.

. The third part of'theapparatus I one ormore so-called accumulators or regis-' tering devices which are controlled in their operation by the-electric circuits completed by the record strip in passing through the selector. A perforationoccurring at; a given or a plurality of. perforations arranged 1n a predetermined a portion of the recorded data or a of the point ,in' the record strip manner. upon the record strip, will complete a predetermined electric circuit or group of circuits when the record strip is, passed through the selector and hence those registering devices which are controlled by these circults will be actuatedto re 'ster and accumulate the data represente by .the pres-' ence of the above-mentioned predetermined perforations in the record strip." Each of the main parts of the apparatus involves novel features of constructionwhich cooperate in a manner which will hereinafter be apparent to cause the apparatus as a whole to operate in an eflicient manner.

The improved apparatus is illustrated in the accompanying drawings, in which Figure 1 is .a plan viewof a terns, in each of which the perforations are arranged in a peculiar manner significant of the data recorded;

Referrin first to Figs. 1, 1 and 2 to 8, inclusive, showing the record strip and the construction of the punching machine for providing the record strip with perforations, it will be noted that the punching machine comprises a frame 1 in which is mounted a transversely-extending punchplate 2 for carrying the series of punches. These punches shown at 3 comprise a series of pins, each of which is mounted to slide in a vertical direction in a corresponding opening formed in the punch-plate 2. Each pin 3 which constitutes the punch proper has a conical head portion 4% against the under edge portion of which bears one end of a coil spring 5. The lower end of each coil spring 5 bears upon the punch-plate and thus each pin 3 is urged upwardly toward an operating lever which is mounted directly above the pin and with which it contacts. These levers are shown in Fig. 2 at 7 to 17 inclusive, and each is pivoted at its rear end to an upstanding lug 18 formed on a transversely-extending support 19. As will be noted from Fig. 3, each of the operatin levers bears upon the pointed conical. hear? 4 of the corresponding punch, and hence when the forward ends of the levers are depressed, the punches will be depressed. Each of the operating levers is provided at its forward end with a finger key constitut-- ing a keyboard, clearly shown in Fig. 2. The finger keys for levers 8 to 17 are shown taken on the at and 1' to 9', respectively. The first lever 7 is a special lever, as will hereinafter vidingthe pressure exerted upon the .keys be the same. Alljof the keys may,

ap' p liedthereto at the'iinger in shape are punched rewound strip on the roll appear, and its fingerkey is desi ated M. There are, therefore, ten keys an a special key provided for the purpose hereinafter v described, but it will be 0 vious that the number of keys may be modified, as desired. It willbe noted that the lugs-18.to which the key levers are pivoted are-disposed in staggered relation. This is for the pur ose' of making the ratio between the two on s of each lever the same for the eleven levers, that is, that portion of the lever to one side of the unch bears the same ratio to the portion of .the lever to the other side of. the punch for all of the levers. The pressure exerted by the levers upon the punches is,

therefore, the same for all of thelevers profinger therefore, be operated by egal pressures eys. he record strip denoted b the reference character A is fed from a 1'0 20. between a pair of relatively thin plates 21 and 22' which direct the record strip under the punch-plate 2 and over a die-plate 23 hav-. ingan'opening 24 lying under each punch. The openings in the die-plate 23 correspond in shapewith the cross-sectional shape of the punches, forced downwardly and enters-the opening in the die-plate, a perforation is punched in :in-shape with the shape of t e punc and t e'die opening.

the recordstri ,corres ond' In the present instance, these are circular and hence circular perforations in the record strip, as will be noted from Figs. 1 and 1.'

The record strip then passes between a pair of feed rolls 25, 26,and then on to a rewinding roll 27 As the diameter of the p 27 constantly changes, the web is preferabl not fed through .the machine by positivey rotating the roll- 27, but bypositively rotating the feed rolls 25 and26. This is accomplished and therefore, asthe punch isby rotating the lower feed roll 26 by means.

of a longitudinally moving carriage. 28 which advancesonestep each time one or more of the lovers 8 to 17 are actuated. The

- carriage 28 is advanced in this step by step manner by means of the escapement mechanism shownin Fig-5. The bar shown a't 29 in Fig. 5 forms a part of a substantially rectangular-shaped frame, pivoted at 31 and 32 in the main frame of the machine and held in its normal position by means of a coil spring 32" serving to hold the rear part of therectangular frame 30 against the lower edges of the key levers. .The bar 29 shown in Fig. 5 forms an extension of the rear member of the rectangular frame 30, as best shown in Fig. 2. When any one of the levers numbered 8 to 17 inclusive,.is depressed, the

thereof will descend into the space between two of the teeth. When the bar 29 is depressed, it serves to depress a plate 35 against the tension of a coil spring 36. The late 35 is mounted upon a pin 37 which sli es in a socket 38. Interposed between the plate 35 and the lower surface of the bar 29 is a small sliding block 39 which is held against slidmg movement longitudinally of the bar 29 by means of a uide 40, but is permitted to slide transverse y of said bar by such guide.

The extremity of the sliding block 39 also corresponds in shape with the space between .two of the teeth, and in the normal position of the parts, such extremityof the block 39 engages between two of the teeth 34, as

bar 29 liesimmediately over such space. The carriage 33 is urged toward the rear of the punching machine b means of a spring 41 which tends to win shaft 42. The block 39 is, therefore, drawn against a stop 43 which limits the rearward movement of the block. A small coil spring 44acts upon the block and tends to move it toward the forward end of the plate-35, but as the strength of the spring 41 predominates, the parts are normally held in the position shown in Fig. 5. When the bar 29, however, is depressed, the plate 35 is deupon a transverse shown in Fig. 5, and the extremity of the 1 pressed and the extremity of the block 39 then moves downwardly out of the s ace .which it occupies between the two eth. The extremity of the bar 29 then assumes the same position which was formerly as sumedby the block 39, that is, it occupies the same space between two of the teeth that i the block 39 occupied. As the block 39 then lies below the plane of the teeth 34, it is free to be drawn forwardly by means of the spring 44. sufficient distance to lie in advance of the bar 29, so that it will be free of said bar, the

When the block 39 is moved a spring 36 forces the plate 35 upwardly caus-' ing' the extremity. of the block 39 to engage between the next two teeth. .As the bar 29 is held. down during the foregoing operations, the carriage 33 remains locked against movement until the depressed key lever is permitted to rise, The spring 32 acting upon the bar 29 then lifts-the latter-above the path of the sliding block 39. Hence, the spring 41 acting upon'the carriage 33 is free to move the carriage rearwardly until theblock 39, which moves rearwardly with the carriage,'.again comes in contact with theQstop 43. The block 39 in moving rearwardly passes under the extremity of the bar 29 and the parts are then again in their nor- I mal positions. It will, therefore, be noted that upon the depression and subsequent release of any of the levers numbered 8 to 17, inclusive, the carriage will advance a distance equal to the distance between two of the teeth at on the carriage. This motion of the carriage is transmitted to the feed roll 26 through a rack bar is formed on the lower part of the carriage 33. The teeth of this rack bar mesh with a gear 46 loosely mounted upon the shaft of the feed roll 26. Positioned adjacentthe gear at; is a ratchet 47 secured to the shaft of the feed roll 26. As the gear 46 is rotated in a counter-clockwise direction by means of the rack bar 45, motion is transmitted from said gear to the ratchet and to the feed roll through the in tcrmediary of a pawl 48 secured to one face of the gear l6 and yieldingly held in en-' gagement with the ratchet teeth by means of movement of the carriage 33, therefore, imparts to the feed roll 26, a step by step rotary motion. When the carriage is returned to its initial position, the ratch 47 and pawl 48 permit rotation of the gear -16 in a clockwise direction without affecting the position of the feed roll 26. Motion is transiuittcd to the upper feed roll 25 through the lower feed roll and the web or record strip passing between the two.

At the rear of the carriage, the teeth of the rack bar 45 mesh with the teeth of a gear 50 (Figs, 3 and 6) loosely mounted upon the shaft of the rewinding roll 27. Adjacent the gear 50 is a ratchet 51 also loosely mounted upon the shaft of the feed roll 27. When the gear wheel 50 is rotated in a counter-clockwise direction by means of the rack bar 45, motion is transmitted to the ratchet 51 through the intermediary of a pawl 52 yieldingly held in engagement with the teeth of the ratchet by means of a spring 53. One end of a flat spiral leaf-spring 5 1, to wit, that end shown at 55, is secured to the ratchet 51, while the other end 56 of such spring is secured to the roll 27. As the ratchet .is rotated by the step by step movement of the carriage, it tends to wind the spring 54, but as the rewinding roll 27 is free to rotate sufiiciently to keep the record strip taut, the spring tends to unwind, thereby rotating the feed roll and winding the record strip thereupon. When the carriage is returned to its initial position, the gear 50 is rotated in a clockwise direction without affecting the position of the ratchet 51. The latter is held stationary during such return movement of the carriage by means of a second pawl 57 which ispivoted to a. bracket 58 secured to a stationary part of the apparatus. This second pawl 57 does not interfere with the rotation of the ratchet during the step by step movement of the carriage,b-u,t merely holds the ratchet stationary during the return movement of thecarriage. As the pawls 52 and 57 both engage the same ratchet, and as the former has to pass the latter during the step by step movements of the carriage, it is obvious that they must be so constructed as not to interfere with each other. In the present instance, at

and, therefore, its leven7 is provided with a notch or opening 59 (Fig. directly over the bar29. Hence, when the lever 7 is depressed, it will have no effect in depressing the bar 29, and, therefore, the carriage will not be advanced. In other respects, the construction of this special key and the punch which it operates is substantially identical with the other keys and punches.

The punching machine above described is designed to produce upon the record strip,

patterns of the type shown in Fig. 1, that is, one or more perforations may be punched in any one or more of a series of ten columns numbered 1 to 110i in Fig. 1. For this purpose, the punches 3are disposed in a straight line transversely of the punching machine. The desired number of perfora-' tions are provided in the record strip in the first column by simultaneously depressing the proper keys, and when such keys are released, the carriage will advance one space causing the record strip to move a sufficient distance, so that the second time one or more of the keys are depressed, perforations will be punched in the second column of the record strip. The special key M is for punching the so-called master hole shown at M in each pattern of Fig. 1. This hole is preferably punched in the first column and at no other place in each pattern of the record strip. The purpose of this hole is to control all of the electric circuits when the record strip is passed through the selector, so that each pattern of the record strip must of necessity reach and be in a predetermined position before the selector can, operate. In a punching machine for producing a. record strip of the type shown in Fig. 1, there are, therefore, eleven keys, including one special key, for punching the master hole M, and ten keys for punching holes or perforations in the positions-in each column numbered 0 to 9,-inclusive. It is obvious, however, that if it be desired to proinstance,

20 '33 may be 0 shown in Fig. 8. It is obvious that in this 40 strip in the machine when such written key is properly planne with re-- spect to the record strip. It is obvious that the 45 tion to be punched.

unching machine may be revised accordlngly tocause the perforationsto be made atthe proper points in the record strip. For it may be, desirable to eliminate themaster hole M and produce the results for which this master hole is intended in some other way. This may be done byspacing the columns of perforations in each pattern of the record strip unequally, as

shown in Fig. 1. Aswill later appear, a pattern in which the perforations are punched in this manner must be in properposition before the various electric clrcuits may be completed in the selector to operatethe accumulators or registering devices. In order to cause the columns of perforations in the record strip to bennequally spaced, as shown in Fi 1", the teth 34 on the carriage successively increasing size, as

manner, each movement of: the carriage 33 will be slightly greater than the preceding movement, and hence cause theirecord strip. 1-25 to move a greater distance at; each movement of the carriage than at the preceding move ment of the carria e.

, .In order to in icat'e -the position of the record strip in the punching machine to make known the columnof-the patterinwhich is in position to be provided with perforations, a so-called pattern plate 60 (Figs. 2- and 3) is provided which isrigidly secured to the carriage ofthe' machine by means of the 35 brackets 61. A pointer 62 is secured to the frame 1 adjacent to said plate. By placing a written or printed key .to the record strip upon the pattern'plate 60, the pointer 62 will indicate the position of the record rinted' or column of he record strip is in posi- It will be; noted-that the gear 46 for driving the feed roll 26 is substantially twice the diameter of 'the feed roll26," and,,therefore, the carriagewill move at each step twice the distancewhich the position of the" plate will indicate whic 50 record strip is fed. This permits theuse of a relatively large key or diagram upon the pattern plate" 60, as the columns upon ,such.

I therefore, the punching machine is COIIStI'IICted toproduce such type of record strip. As

columns of spaces at anywhere apparatus is capa 'The 0 position may or may not be umn numbered i to perforations. in the The type of record strip which perforations may be provided and each column, except the first, may comprise from one toten perforations. The points in these columns at which the erforations may occur are numberedin' ig. 1 as O'Ito 9,-"inclusive. In the first column, the master hole M is punched and, therefore, the first column may comprise eleven perforations.

The manner 1n which the perforations are provided in the record strip and the number of such perforations will depend upon the data which is tobe recorded. The present le of -a large number. ofd and subsequently regisuses and-may reco kinds, but for the sake of ter data of many illustration,- let it be assumed that the ap-- paratus-is to be used-in a store for recording data relatingto the various transactions. Each pattern on the record strip would. then, correspond with one transaction, that is,'the

perforations in the record strip representing the data for any given-transaction willconystitute one pattern. There are four of these 'patterns shown in Fig. 1, in each of which :the solid black circular areas represent holes or perforations punched in the record strip. The 0th er'positlons marked on the recormh strip are merely to'show the location at which other perforations might occur.

' The relation between the number and ar-v rangement of the perforations in each pat tern will depend upon the system adopted by the users of the ap ratus. In other words, it will rest with't e users'of the apparatus to determine the number and location of the perforations for any certain item tobe recorded. For instance, some such system as follows might four spaces numbered 0', -1, 2 and 3 in column 1' of each pattern and all of the spaces in from 0 to 9, inclusive, for the date of the transthe second column might be reserved action. As the first number in any date never exceeds 3, only the first four spaces in the first column are needed for this data. (punched depending uponthe-system adopte by the users. The last six'ispaces in the first col- 9, inclusive, may be reserved for the number. of the salesman. The salesman-ma be given the numbers 4 to 9, inclusive, an any comb' ation of such numbers, such, for instance, as 4'-5. Theperforations punched in column 1 of pattern No. 1, under such conditions, would indicate that the salesman involved is No. 4-5. By

showing that a very small space is needed on the more strip to record the number of-a large number of'salesmen.

The date indica d by the perforations in be adopted. The first as a perforation occurs in the position numbered 8 of column 2. As the 0 position is punched in column 1, the date may be read 0 8. In pattern No. 2, the date indicated by the perforations is the 15th day of the month, as a perforation occurs at position 1 in column 1 and position 5 in column 2.

The third column of each pattern may indicate the particular account involved, that is, the position marked 0 may indicate the cash sales, position No. 1, cash refunds, position No. 2, sales on account, 'etc. Here again the perforations may be provided in different combinations, thus making it possible to record a large number of different kinds of accounts. I

Column/l may be reserved for the class of goods, columns 5 and 6 for the quantity of material in the transaction, and the remaining columns for the'money value of the transaction. It will be noted that two or more columns according to this exemplary system are reserved for numbers containing more than one digit, for instance, perforations provided in the last four columns may indicate the mono value of the transaction to be as high as 99.99. The money value of the transaction represented by pattern No. 2 would, according to this system, be $23.57.

Obviously, the above systerr of punching the record strip may be varied according to the purpose for which the apparatus is used and according to the manner in which the users of the apparatus desire the number and location of the perforations to be related to the data to be recorded; By adopting some such system as that described above, however, amount or variety of information can be recorded without unduly increasing the relative proportions of the record strip shown in the drawing. For instance, by using the positions in combinations of five in three columns, over 16,000,000 combinations are possible.

At anytime that it is desired to register or accumulate data recorded upon the record strip, the latter ispassed through the selector constituting the second part of the apparatus considered as a whole. From the following description of the selector, it will be seen that the same may cause the accumulators or registering devices to accumulate and indicate in numerical figures, all of the data recorded upon the record strip or certain parts thereof, depending upon the setting of the selector. Thus, if at any time it is desired to know all of the data recorded upon the record strip, the same may be pa$ed through the selector, andif the latter is properly set to take off all of the data from the record strip, the accumulators will indicate all of such data. If it be desired to know only the total quantity of mastrip isillustrated in Figs. 9

it is obvious that practically any terial sold, the selector may be so set as to take off this data from the record strip and none other. Furthermore, any combinations of data may be taken off the record strip if the selector be properly set for this purpose, for instance, it may not only be desired to know the total quantity of material sold during the given period, but it may also be desired 'to know the money value of the transactions involved, and these two combinations of data or any other combinations may be taken from the record strip and indicated by the registering devices by merely setting the selector in a predetermined manner, as will hereinafter appear, and passing :the record strip through the selector until all of those patterns have passed through the selector which represent the total number 3f transactions for which the data is desire The selector for taking off the data represented by the perforations in the record and will now be described.

In its referred form, the selector com prises a ramework, denoted as a whole by the reference character 63, .(Fig. 10), which supports a surface 64 over which the'record stripis assed. At one side of the surface 64, the amework 63 supports a rotatable spool 65 from which the record strip may be unwound and wound upon a second spool 66 disposed at the opposite side of the surface 64. The spool 66 upon which the record strip is wound ma be rotated by hand, or in an other suitab e manner.

Accor ing to one form of the invention, the surface 64 is of electric non-conducting material, but is provided with a plurality of separate sections of conducting material to 19, inclusive,

corresponding in number and location with I the various positions of the record strip which are capable of being punched. Each of these conducting sections is connected by an electric conductor to a corresponding socket on a so-called terminal board, so that there is provided one of such sockets for each conducting section on the surface .64. The sockets are capable of being connected, by means of conductors having plugs insertible in the sockets, to the or registering devices, as will hereinafter appear. Brushes are supported over the conducting sections on the surface 64 in such a way that currentsupplied to these brushes is conducted through those conducting sections which register with perforations in the record strip, and thence through the termiaccumulatorswhich erforations in the record strip register. his will be made more clear as the specification proceeds.

Preferably the surface plurality of selector bars,

64 is madeup of a one end of each of which is relatively wlde, as shown at 67 in stead of being located as face and half on the other side. Two upper parallel beams 69 and 7 0 of the framework 63 have the crow-sectional shape shown in Fig. 13, that is, their cross-sectional shape is somewhat analogous to the cross-sectional shape of an eye-beam. Each of such beams 69 and 70 have openings 71 cut in theirlower portion, which openings extend completely through the lower horizontal portion 72 of .the beams and through the vertical web portinv 73 thereof, but do not extend through i the upper head portion 7 4. As will be clear from Fig. 13, these openings are spaced apart a distance equal to the width of the narrow .part 68 of the selector bars and each opening is equal in width to the width of such narrow ortion of the selector bars. The selector ars are assembled by inserting the narrow end 68 of the first selector bar s in the first opening 71 and sliding the same longitudinally until the shoulders75 (see Figs. 12 and 13) rest upon the two ledges 76 (Fig. 13) adjacent the opening in which the bar is inserted. The openings 71 are so formed in the two beams 69 and 70 that the ledges 76 of one beam will lie directly opposite the openings of the other beam. Therefore, when the first selector barassumes its final position, the extremity of, the narrow portion of the bar will rest upon a ledge whi h is directly opposite the opening in which 'the' selector bar is inserted. This ledge is shown at 76' in Fig. 12. The sec- 0nd selector bar a is inserted from the other sideof the surface 64,;that is, its small end beam until its shoulders 75 rest-upon is' inserted through an opening in'the other the ledges adjacentv such opening and i until the extremity of its narrow portion rests upon the ledge 7 6 at the inner side of the other beam (Fig. 12). The third selector bar a" is insertd from the same side as the selector'barsf. One of its shoulders 75 inthe final position of the 'selecto'fbar will acent shoulder of the occupy part of the ledge occupied by the adat 68. The nar-'" central surface 64 isformed adjacent selector bar 's, as clearly shown in Fig. 12 and the adjacent edges of the wide, portions 67 of these two bars will be contiguous. Likewise the adjacent edges of the two narrow portions 68 of the two bars 8' and s will be contiguous. The other shoulder7 5 of the bar a will rest upon part of the next ledge and the extremity of the small end of the selector bar will rest upon a ledge 76 opposite the opening in which the selector bar 8 is inserted. By inserting'the bars in this manner first from one side of the surface 64, and then the other, the

the closely I b adjacent narrow portions 68 of the selector bars, and at either side of such surface, a surface or table is formed of the closely adjacent wide portions 67 of the selector bars. The outer ends ofthe selector bars 8', s, 8?, s" and s are supported on a ledge 77 (Fig. 10) formed in an upper beam 78 at one side of the framework 63 and the outer extremities of the selector'bars s, 3, 8, 8 and 8 are supported on a similar, ledge not shown in the drawing the otherside of theframework corresponding to the beam 78..

As best shown in .Fig. 9, the n'arrowwportions 68'of the selector bars are provided with a series of electric'conducting sections corresponding in numberIand position tothe positions of one column. on the record strip.

For instance, the first selectorbar s is pro vided with eleven conducting sections corresponding to the eleven positions of the first columnof any pattern on the record strip at which perforations might occur.

Ten of these conducting sections 0" to 9" but formed in a beam at correspond to positions. 0 to 9 of the record strip and the other conductingMsection M" corresponds 'withthe position where the fmaster hole occurs. The second selector. bar a is provided with only ten. conducting sections 0 to 9" corresponding to the positions 0"to 9 in the second column of the rec-' ord strip pattern. Likewise all of the other selector bars are provided withten conducting' sections corresponding in position to the positions at which perforations might occur in the record. strip. It will be un rstood that the selector bars are composed o material which will not conduct electricity, but that the conductin sections will conduct electricity and for t is purpose they may be made of copper or any other suitable conducting materiah There, therefore, occurs onthe surface 64, a conducting section for cachposition of 'a pattern on the record strip at which a perforation might occur, so that i if the record strip is in proper position, and

.if all of the positions in a pattern of the record strip were unched, the perforations would register with the conducting sections, and there would be one conducting section for each'perforation. p

The conducting sections. may be made of any suitable material which will conduct electricity, but they are preferably made of copper and pass completely through the selector bars, as shown in Fig. 10, so that they may be connected by wires below the selector bars and leading to the terminal boards.

The wide portion of each selector bar has a series of sockets corresponding in number with the conducting sections on the narrow part of the selector bar. For instance,the first selector bar 8 has eleven sockets, the first of which -M"' is by means of a wire or conductor to the conducting section M. The second socket 0" is electrically connected to the second conducting section 0" of the same selector bar, as clearly shown in Fig. 10. The third socket 1" is connected to the third conducting section 1" of the same selector bar, and likewise all of the other sockets of the selector bar 8 are electrically connected by means-of conductors to the corresponding conducting sections at the narrow end of the selector bar. Eachof the other selector bars has only ten sockets corresponding with the ten conducting sections at the narrow end of the bar. On the second selector bar 8 the sockets 0" to 9" are electrically connected by means of conductors to the corresponding conducting sections on the narrow end of the bar. Likewise, the'sockets in each of the other bars are electrically connected by means of conductors to the conducting sections on the narrow ends of such bars. It will, therefore, bev

seen that each conducting bar comprising the wide end-with its sockets and the narrow end with its'conducting sections is self-contained and that each of the bars, together with the conductors at its under side which connect the sockets with the conducting sections, may be removed and replaced as a unit. The conductors at the under side of each selector bar may be bound together so that they will occupy a small space and not exceed in width, the width of the narrow end of the selector bar.-

A contact brush either of the form shown at"? 9 in Fig. 15, or 80 in Fig. 16, is adapted to be supported on the beams 69 and 70 over any one of the columns of conductin sections on the surface 64. The brush 79 s own' 1n Fig. 15 has a plurality of closely R tioned depending wires 81 of sufliclent length to make contact with the conducting sections on the surface 64 when the brush is supported on the beams 69 and 70. These wires 81 are mounted in a bar 82 capable of reaching from the beam 69 to the beam 70. The brush is positioned by resting the extremities of the bar 82 on top of the beams 69 and 70, as shown inFig. 10, and maybe held against accidental displacement by means of depending pins 83 at the extremity of the .bar 82 which are adapted to e in corresponding openings formed in :Ee

electrically connected are connected to 92, inclusive,

top of the beams 69 and 70. At each end of the bar 82, there is a plug 84 of electric conducting material, and these plugs are electrically connected, by means of a conductor which does not show in the drawing, to allof the wires 81 of the brush. Therefore, if either of the plugs 84 be connected with a source of electric current, the current will flow through the wires 81 of the brush and through those conducting sections on the surface 64 which register with a perforation 1n the record strip, provided the electrical lower ends, as hown at 87 in Fig. 11, so as not to injure the record strip. The upper end of each of the spring contact fingers 85 extends above the bar 82,.and serves as a plug to which a socket on the end of a conductor may be connected. It may sometimes be necessary to use both types of brushes at the same time, as will later ap ear. Both types of brushes are shown in igs. 9 and 10, as the setting of the selector illustrated in these figures requires the use of both t es of brushes.

' addition to the sockets of the terminal board that are carried by the selector bars, there are provided a number of additional or extra sockets shown at 87 to 92, inclusive. These sockets are provided in a stationary part of the framework. Two of these sockets, for instance, those shown at 87 and 88, may be permanently connected to a source of electric current, such as the battery B, and others of said sockets, at 90, 91 and 92, may be connected to the accumulators or registering devices by -means of the conductors 93, 94 and 95, respectively. As will hereinafter appear, these conductors to' those accumulator units which it is desired to actuate by the passage of current through certain of the conductin sections on the surface 64. The sockets 8 may be connected to the other sockets of the terminal board by means of conductors having at their extrem1-. sultable plugs for insertion in the ties, sockets. Likewise any of the'sockets of the terminal board may be connected to the brushes positioned over the surface 64 by means of conductors having plugs at one end for insertion in the sockets, and-sockets at the other end for connection with the plugs 84 on the brushes 79 or the plug-likeextremities of the spring contacts 85 of the such as those shownthe terminal board. The nine conductors the terminal board, and

As will be noted from it should be here noted that each' accumulator unit has nine electro-magnets, for the purpose hereinafter described. When any one or more of the accumulator unitsis being used for registering and accumulatin data, each of the magnets of such accum ator or ac-.

cumulators is connected by means of a conductor to one of the socketsof one 581165011 leading to one accumulator unit for the nine magnets therein are preferably bound toget er to form a single cable. One of these cables leading to the accumulator unit a is provided at its end with 98 adapted to slip into the soc ets ,0 any series of sockets on the terminal board. For this purpose, the lugs are spaced the same distance apart as t e sockets. The length of plug bars 97 may vary and the number of p ugs which they carry mayvary to suit requirements, but preferably they are provided with nine p sockets of any series numbered 1". to 9".

and each is connected with one of the nine conductors making up the cable 96. In this way, current may beconducted' from any one of the conducting sections on the surface 64 through the corresponding socket of the then through that conductor of thecable which is" connected-to such socket to the proper magnet in the'Fac- 1g. 19,-the plu bar 97, in addition to having the plugs 98, as at its upper side, a series of sockets 99 in which the plugs' may be inserted of a second lug baridentical with that just described. his second plug bar .97 .is

shown in Fig. 19 immediately above the plug is also composed of nine conductors, which at one end are connected to the nine magnets in the accumulator unit e and at the other. end to the nine lugs of the'plug bar. The is shown in the drawings ied to the series of sockets in the selector 1' 8 and the second plug bar 97 is applied to the series of sockets in the first lug bar 97 As will later appear, these -plu bars are applied to that series of sockets 'in 518 terminal board through which it is known that current will pass to the accumu- {lator unit's.

bar 101. to accumulator unit 12 and a similar cable 103 runs from plug bar 101' to accumulator unit f. It will be understood that these cables are made u of conductors connected with the series oi plugs and with the magnets in the accumulator units in the same manner as described above in connection with the plug bars 97 and 97. It will also be understood that these plug bars may be applied to any series of sockets in the terminal board depending upon the type of data -to be taken off the record strip. Figs. 9 and 10 show the parts of the selector arran ed for onl one setting out of alarge num er of possi 1e settings. In Figs. 9 and 10, the setting of the selector or, in other words, the

arrangements of the brushes and plug bars the bar 101 being applied to the series of sockets in the selector bar a and and various electrical connections 15 such that only certain data will be taken off the record strip, as will hereinafter appear. The other electric conductors shown in Fi 9 and 10, but not hereinbefore speci cally described, will be referred to'later when the specific setting of the selector is referred to and described.

It is obvious that it may often be 'desirable to have only one plug bar positioned over a series of sockets in the terminal board,

bar of the type shown in which case a plug in F i '17 and 18 maybe employed in which the pugs 98 are substantially like the plugs 98 of the lug bars hereinbefore described, but no soc ets are provided at the top of the plug bar in which the plugs of another plug bar may be inserted.

In Fi 14, there is illustrated a modified "form 0 selector bar in which the abovedescribed individual conducting sections 0" to 9" are replaced by a single strip of conshown at 104. his con- As will hereinafter 11 occur in a predetermined column of the record strip, regardless'of the exact location of the perforations inthe column. In other words, a perforation occurring at any, position in'the column will permit an electric circuit;- to be completed through, the conducting strip 104. The registering cumulator units are as shown in Fig}? 20 ferring first .to' i noted that each 0 devices or so-called acpreferablyconstructed to 26, inclusive.

The peripheral ed portion of the open side of the casing isslightly flared or enlarged, as shown at 108, so that such flared portion of each casing may slip part way over' the closed side of the casing of an adjacent unit when the units are assembled or closely positioned, as shown in Fig. 21. In

this way, the rear wall 109 of one unit constitutes the front wall of the adjacent unit. The said wall 109 of each unit 15 provided with a boss 110 forming a bearing for the journal 111 of a toothed disk 112. The extremity 113 of the shaft of the disk 112 is substantially square in cross section, as best shown in Fig. 20, and is adapted to be received by a correspondingly-shaped opening 114 formed in the journal 111 of the toothed disk of the adjacent unit. In this way, all of the toothed disks of all of the units are positively connected and rotate in unison.

They may be rotated in any suitable manner, and when so rotated, serve to transmit rotation of the counting disks through the intermediary of the mechanism presently to be described. In Fig. 21, two accumula-' tor units or registering devices are shown, the first of which, denoted generally by the reference character a, will be hereinafter referred to as the units accumulator and that designated by the reference character 6 will be hereinafter referred to as the tens accumulator. The invention contemplates the use of as many of these accumulator units as may be necessary, but for the sake of illustration, only the units and tens accumulators or registering devices 7 will be referred to. The counting disk for the accumulator unit'a is shown at 115 and that for the unit shown at 116. Fach of these disks is loosely mounted upon a hub-like portion 117 formed on the shaft of the toothed disk 112.

Associated with the periphery of each of the counting disks is a series of numbersfrom 0 -to 9, which numbers are capable of being brought into position to be viewed through openings 118 formed in the front of the accumulator There is one of these openings for each accumulator unit, as best shown in Figs. 21 and 26 into registry with which'the numbers on the corresponding disk may be succemively brought.

Mounted upon the face of the counting disk in each accumulator unit is a series of radially-disposed sliding bars 119. From Figs. 20 and 21, it will be noted'that these bars are mounted upon the face of the disk adjacent the corresponding toothed disk. There are ten of'these sliding bars, there being one of the same for each of ten teeth provided on'the toothed disk 112. As the counting disk shown in Fig.20 is partly broken away to expose underlying mechapear in this figure, as the remaining three bars are carried by that portion of the disk which is broken away. Each of the sliding bars is slidably mounted upon the disk by means of two straps 120 in which the bars are capable of a limited sliding movement. The movement of each bar is limited by means of a pin 121 secured to the bar, which pin by contacting with either of the straps 120 limits both the inward and outward movement of each of the bars. The movement of each bar is such that in its extreme inward position, the inner extremity of the bar reaches substantially to the bottom of one of the teeth on the disk 112 and in its outward position, the inner extremity of the bar will .e clear of the teeth of the disk 112. As will be clear from Fig. 20,'the sliding bars 119 are so disposed that when any one of the same is forced inwardly, it will be engaged by one of the teeth of the disk 112, thus causing the counting disk to rotate. In order to yieldingly hold the sliding bars l19'against accidental displacement in their extreme positions, a small leafspring 122 is secured to each of the innermost straps. Only one of these springs is shown in Fig. 20, and it will be understood that the springs for the other sliding bars are analogous in construction. The extremity of the spring 122 is bent inwardly and is capable of lightly engaging in either one or the other of two small recesses 123, depending upon whether the sliding bar is in its inward or outward position.

Slidably mounted upon the rear wall 109 of each accumulator unit is a series of plungers numbered 124 to 124. There are nine of these plungers mounted in a circular series about the sliding bars 119. They are substantially 36 apart, except in the case of plungers 124 and 12 1, which are 72 apart. Inother words, there is no plunger located at the point where the tenth plunger would be located if there were one of these plungers %)10V1ded for each of the sliding bars ach of the plungers just described is mounted in a strap 125 and is yieldingly urged inwardly by means of a coil spring 126 reacting against the strap 125 and a shoe 127 provided on the plunger. The plungers are normally prevented from moving inwardly by means of a shoulder 128 provided on each shoe 127, which is normally engaged by a corresponding shoulder 129 formed on a catch lever 130. There is, therefore, one of these catch levers 130 for each of the nine sliding plungers and each is actuated by an electro-magnet positioned in the casing of the accumulator unit. There are, therefore, nine electro-magnets which constitute the magnets above referred to that are controlled by the passage ofthe record strip through the selector. The magnet which controls the catch lever for the sliding plunas shown in Fig. 20.

gn'et for t e catch lever of the plunger 124 is shown at 131, and so on, the last magnet for the catch lever of plunger 124 being numbered 139. The electro-magnets are, therefore, numbered "131' to 131. are energized, they attract corresponding armatures shown at 132' to 132. The armatures are ivotally connected to levers 133 to 133 whic 'themselvesare pivotally mounted on the rear Wall 109- of the accumulator unit,

er 124' is shown at 131', the ma are operatively connected with the corresponding catch levers 130, so that upon ac.- tuation of any electro-ma'gnet, the corresponding catch lever-will be actuatedto dis engage the shoulders 128 and 129 and permit the correspondin plunger to inove to its inward position. he inward movement of each plunger is limited by a. head. portion 134 formed upon the lunger which contacts with the strip 125.. Y en any one of the plungers is moved-in this manner to its inward position, its shoe 127 en ages the extremity of the underlyin sli in and forces this bar inwardl extremity is in position to beengaged' by one of the teethof the disk 112.

After release of anyone iding plungers 124 to 124, such lunger stays in its Inward position until it is forced back by a cam-likeportion formed upon the countlng' disk. As from Fig. 20, portions formed on the .counting disk bei tween each two sliding bars 119. These camlike portions, as prise a struck-up portion 136, the outer camlike edge 137 of each of which is capableof passin directly under the shoes 127. After.

any sliding plunger moves to its inward position andthe counting disk starts to rotate,

. J the oncoming struck-up portion'136 serves as a 'cam and engages with the shoe 127 of such plunger to move the plunger outwardly and restore the same to its initial posltlon.

"The shoulders 128 and 129 on the shoe and catch lever respectively then ,reengage to holdthe plunger in its normal position. It

will, therefore, be understood that the cams ,or struck-up ortlons 136 are so located on the count'n'g disk that-when the plungers 124' and 12 sition, such cams will have no effect upon the position of the shoes 127, although it is de- 1 sirable to causethe cam-like edge 137 of such 'struck-upportions to slide lightlyag'ainst the shoes to produces. braking effect forthe counting disk to arrest its motion,

Associated with each .casin of the accumulator units is a series of soc ets numbered 138' to 138. Each of these sockets is connected by means of a conductor to one of the Inthe present instance, only three magnets. of these conductors are shown, to wit, those 7 with magnet 131, socket 138 to magnet 131*, 138to magnet" 131; The other conductors are omitted as they would only serve to confuse the drawing. All of the magnets are connected to a .common'return conductor 139 which leads to the selector. The sockets 138 to 138 are spaced apart the same distance as the sockets on the terminal board, so that the plug bar of the type shown in Figs. 17 and 18 may be emp oyed for cooperation withsuch sockets 138 to 138. It is, therefore, evident that separate electric circuits may be completed from the selector throu the several electro-magnets 131' to 131. s above stated, the accumulator units are closely positioned, as shown in Fig. 21, andwhen so ositioned means' is provided for causing t e counting disk of one unit to 00-.

operate with the counting disk of the-second unit, so that when one disk, for instance, the units disk,-approaches one completerevo it will cause' a partial rotation of the ten's disk. The mechathis is herein remg mechanism, and

i'ch the units may be rigidly secured by means of bolts or other fastenin'g devices 141 (Fig. 21). a.

This carrying mechanism comprises for each accumulator unit, a sliding rod 142 mounted upon-the rear wall 109 of the aconeof these in Fig. 21, and each is 'slidablyheld upon the rear wall 109 of the corresponding acbrackets it m Fig.

143 and 144; As will ben 20,- this sliding rod is posing tween the. two plungers 124 andl24. mally held in-aretracted' position and is released by the countin disk in the adjacent accumulator when't clatter approaches When' thus released, the sliding rod 142 moves one of the sliding bars 119 of the same accumulator and socket V igs. 22 to 25,-inclusive.v

It will be understood portlons 136 project units are preferably mountedppn a common support shown at 140m as shown a Bubstani inwardly, thus setting the counting disk of that accumulator in rotation. This counting disk is arrested in its motion, after it has moved one space in order to bring the next higher number into registry with the opening 118. For instance, if the units counting disk 115 makes one revolution, the sliding rod 142 of the adjacent tens accumulator is released and moves an adjacent sliding bar 119 inwardly, thus causing the tens disk 116 to rotate one space. This brief description of the operation of the carrying mechanism is given for the purpose of making the following detailed description of its construction and operation of each of its parts clear and obvious.

The detailed construction of the carrying mechanism for one accumulator unit only will be described, as the carrying mechanism for all of the units is constructed in a similar manner. As will be noted from Figs. 22 and 25, the sliding rod 142 is yieldingly urged toward the axis of the counting disk by means of a. coil spring 145 which acts upon a collar 146 secured to the rod 142 and reacts at its other end against the bracket 144. Adjacent the collar 146 is positioned a sleeve 147 which is slidably mounted upon the rod 142, but is not capable of rotating thereon. This sleeve is yieldingly urged toward the collar 146 by means of a second coil spring 148 which reacts against the bracket 143. The strength of the spring 145 predominates and the tendency is for the rod 142 to move inwardly toward the axis of the counting disk, but this is normally prevented by two pivotally-mounted retaining segments. One of these is shown at 149 which normally engages with the inner side of a lug 150 carried by the sliding bar 142. It will be noted from Fig. 24 that this retaining segment 149 has a projecting portion 151 which extends rearwardy through a slot in the rear wall 109 of the accumulator unit. It also has a projecting portion 152 which is capable of moving into and out of operative relation with the lug 150. The segment 151 is normally retained in its operative osition shown in Fig. 24 by means of a l eafspring 153. The second retaining segment shown at. 154 also has a portion 155 which projects through a second slot or o ening m the rear wall 109 and has a pro ection 156 capable of moving/into and out of operative relation with a lug 157 carried by the sleeve 147. The retaining segment 154 differs from the retaining segment 149, in that it has an elongated" portion 158 projecting away from the rear wall 109 and toward the inner side of the counting disk. A leaf-spring 159 acting upon the inner side of this elongated portion 158 serves to yieldingly retain the segment in the position shown in Fig. 23. It isnow obvious thatif both of the retaining segments just described be actuated by causing the counting disk of the accumulator to act upon those portions of the segments which extend through the rear wall 109, the sliding rod 142 will be, released and will move inwardly. The means for accomplishing this takes the form of two projections 160 and 161 mounted upon the outer face of the counting disk (see particularly Figs. 20 and 21). These projections are so mounted on each counting that when the 0 of such disk is visible, they will occupy the position shown in Fig. 20. Therefore, just before such disk completes a full revolution, these projections will act upon the retaining segments 149 and 154 of the adjacent accumulator to release the sliding rod 142 of such adjacent accumulator unit. For instance, if the 0 of the units counting disk is visible through the opening 118, the projections 160 and 161 of this disk will occupy the position shown in Fig. 20 just below the sliding rod 142. When this units disk has nearly completed its full revolution and just before the 0 again registers with the opening 118, such projections will act upon the portions of the segments 149 and 154 which project from the tens accumulator, thus releasing the sliding rod 142 of the tens accumulator and moving one of the sliding bars 119 which lies adjacent such sliding rod inwardly to cause the tens disk to rotate. As will be noted from Figs. 22 and 25, in each stationary position of the counting disk one of the sliding bars 119 lies immediately adjacent and parallel to the sliding rod 142, and when'the rod 142 is released as above described, such sliding bar 119 is moved inwardly through the intermediary of a projecting finger 162 at the end of such sliding rod (see Fig. 25). When the tens disk is set in operation as just described, it will rotate until the pin 121 on the bar 119, which has been moved inwardly, engages with a cam 163 projecting from the rear wall 109 of the accumulator. The position of this cam is shown in Fig. 20, from which it will be noted that the tens disk, or any disk which is set in operation after a full revolution of the preceding disk, will move but one space.

The inward movement of the sliding rod 142 is limited by reason of the fact that the lug 150 contacts with the end bracket 143 in which the sliding rod 142 is mounted. \Vhen the retaining segments 149and 154 are actuated in the manner above described and the sliding rod 142 moves inwardly, the projecting portion 152' of the segment 149 rests on the top edge of the lug 150. The projecting portion 156 of the segment 154- in the inward position of the sliding rod, 142, engages with the outer side of the projection
